ANCHOR FOR OYSTER-BRUSH.

SPECIFICATION forming part of Letters Patent No. 643,092, dated February 6, 1900.

' Application filed December 28, 1899. Serial No. 741,793. (No model.)

To all whom it may concern.-

Be it known that I, ANDREW B. HENDRYX, of New Haven, in the county of New Haven and State of Connecticut, have invented a new-Improvement in Anchors for Oyster- Brush; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a side view of an anchor c011- structed in accordance with my invention; Fig. 2, a sectional view of the mold in which the anchors may be formed; Fig. 3, a transverse section of the same.

This invention relates to an improvement in anchors for oyster-brush, such as are employed in the propagation of oysters in accordance with my invention for which Letters Patent No. 611,199 were granted to me September 20, 1898. The invention set forth in the said Letters Patent involved the use of a brush with an anchor adapted to be secured thereto by a flexible connection. As set forth in the specification of the said patent, the anchors were preferably formed from a thin metallic shell filled with sand, the object being to provide an anchor which would in course of time become destroyed and not obstruct or encumber the bed.

The object of this invention is to form an anchor which is less durable than a metal shell and one which is more readily and cheaply formed; and it consists of a bag or casing of sand surrounded by a wire loop and inclosed in a casing of cement, as more fully hereinafter described, and particularly recited in the claims.

As herein shown, the anchor consists of a bag A of paper, cloth, or other light material filled with sand and closed in any suitable manner. Preferably the bag will be surrounded by strands B of wire, which are twisted about the neck C, so as to firmly close the bag, and thence extend upward, forming a loop D. The bag thus filled and closed is placed within a mold E, of Wood or other suitable material, having a chamber F larger than the dimensions of the bag, and the space around the bag is filled with cement, which isallowed to harden and completely incase the bag. Preferably and as herein shown the inner walls of the chamber F in the mold E will be formed with a number of lugs or projections a, which will properly support the bag and hold it out of contact with the walls of the chamber, and so as to provide a space entirely around the bag. As soon as the cement hardens the mold is removed and the loop D forms a convenient means for securing the anchor to the brush.

Anchors of this kind may be readily formed along the shore as required, and preferably dry sand will be employed, as it will absorb more or less of the moisture from the cement when poured into the mold, and thus assist in the hardening thereof. An anchor of this character is sufiiciently strong to hold the brush until it becomes so water-soaked or loaded with oysters as to become implanted in the bed, by which time it has served its purpose and is then useless. By this time the cement will have disintegrated and allowed the sand in the anchor to escape. The addition of this sand to the oyster-bed is not objectionable, but on the contrary is a very desirable feature. Furthermore, the oysterset will adhere to the anchor, and this in itself will have a tendency in time to break the cement shell.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. An anchor for oyster-brush consisting of a body of sand inclosed in acasing of ce ment, substantially as described.

2. An anchor for oyster-brush comprising a body of sand temporarily inclosed, wires secured to said closure and extending upward above the same, and a casing of cement surrounding said body of sand, substantially as described.

In testimony whereof I have signed this specification in the presence of twosubscribing Witnesses.
